[0068] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of this application, "a plurality of" means two or more unless otherwise specifically defined.

[0069] In this application, unless otherwise clearly specified and defined, terms such as "installed", "connected", "coupled", "fixed", etc. shall be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or integrated; it may be a mechanical connection, an electrical connection, or communicable with each other; it may be directly connected, or indirectly connected through an intermediate medium, and may be the communication inside two components or the interaction relationship between two components, unless otherwise clearly defined.

In addition, without contradiction, those skilled in the art can combine and combine the different embodiments or examples described in this specification and the features of different embodiments or examples.

[0072] The embodiment of this application provides a roller brush 10 and a cleaning device 100. Among them, the roller brush 10 is used to directly contact the surface to be cleaned when the cleaning device 100 performs a cleaning operation, and perform a cleaning process on the surface to be cleaned.

[0073] The cleaning device 100 may be a floor scrubber, or a floor cleaning device such as a sweeping and mopping robot or a sweeping robot for cleaning the floor, or a cleaning device for cleaning walls, windows, etc.

[0074] It is understandable that the cleaning device 100 may be a device that can clean the cleaning surface to be cleaned by means of a roller brush, see Figure 1 , Figure 1 A partial structural diagram of the cleaning device 100 provided in an embodiment of the present application. When the cleaning device 100 starts working, the cleaning device 100 can automatically deliver cleaning liquid to the roller brush 10. The roller brush 10 can generate a certain friction with the surface to be cleaned by rotating. The friction and the cleaning liquid can quickly separate the dirt on the surface to be cleaned from the ground, thereby effectively removing the ground stains. At the same time, the cleaning device 100 also has a recovery module for sucking sewage. The recovery module includes a sewage tank and a motor. When the motor is working, the sewage tank connected to the roller brush 10 through the sewage suction pipe can be in a negative pressure state, and the cleaning liquid with dissolved stains can be sucked into the sewage tank through the sewage suction pipe.

[0075] In the related art, the cleaning device 100 needs to select and replace different types of roller brushes 10 according to the degree of dirtiness of the ground and the type of the ground to be cleaned.

[0076] For example, when the floor to be cleaned is highly dirty, a roller brush 10 with strong cleaning power, such as a roller brush 10 with hard bristles, can be selected as needed; when the length of dirt on the floor to be cleaned is short, a roller brush 10 with relatively moderate cleaning power, such as a roller brush 10 with softer bristles, can be selected as needed. Alternatively, when the floor to be cleaned is a tile floor or marble floor with a high degree of wear resistance, a roller brush 10 with hard bristles or a roller brush 10 with softer bristles can be selected according to cleaning needs; when the floor to be cleaned is a wooden floor or micro-cement floor that is not wear-resistant, in order to avoid damage to the floor during the cleaning process, a roller brush 10 with softer bristles needs to be installed. For users, the need to manually replace the roller brush 10 is not only cumbersome to operate and burden the user's daily cleaning, but also causes stains on the roller brush 10 to stain the user's hands to a certain extent, and may also cause secondary pollution, and ultimately affect the user's experience.

[0077] In order to solve the above problems, an embodiment of the present application provides a roller brush 10, which can effectively overcome the above problems and improve the user experience.

[0078] Specifically, the roller brush 10 provided in the embodiment of the present application includes a drum 1, a first cleaning component 2, and an adjustment component 3. The drum 1 is an overall hollow columnar structure, and a cavity 101 is provided therein. The adjustment component 3 is located in the cavity 101. A plurality of mounting grooves 102 communicating with the cavity 101 are also formed on the circumferential side wall of the drum 1. The first cleaning component 2 is slidably engaged with the drum 1 through the mounting grooves 102 and is connected to the adjustment component 3 located in the cavity 101.

[0079] Driven by the adjustment component 3, the first cleaning component 2 can extend or retract relative to the drum 1 along the radial direction of the drum 1 through the mounting grooves 102.

[0080] Specifically, the adjustment component 3 can move between a first position, a second position, and between the first position and the second position. When the adjustment component 3 is located at the first position, the first cleaning component 2 is located on one side close to the central axis of the drum 1; when the adjustment component 3 is located at the second position, the first cleaning component 2 is located on one side away from the central axis of the drum 1.

[0081] It should be noted that the first cleaning component 2 can slide relative to the drum 1 in the radial direction driven by the adjustment component 3. At this time, the mounting groove 102 itself has a certain thickness, which can be used to play a certain guiding role in the movement of the first cleaning component 2. The adjustment component 3 can provide a force for the first cleaning component 2 to slide relative to the mounting groove 102 by moving along the axial direction of the drum 1, and drive the connected first cleaning component 2 to slide relative to the mounting groove 102.

[0082] In the embodiment of the present application, a second cleaning component 6 is provided on the outer surface of the drum 1. When the adjustment component 3 is located at the second position, the first cleaning component 2 extends relative to the mounting groove 102 and is at least flush with the second cleaning component 6.

[0083] When the adjustment component 3 is located at the second position, the first cleaning component 2 can be flush with or extend relative to the second cleaning component 6 located on the outer side wall of the drum 1. When the drum 1 is used for cleaning operations, the above-mentioned first cleaning component 2 can directly contact the surface to be cleaned, such as the ground, and perform cleaning operations on the ground. Correspondingly, when the adjustment component 3 is located at the first position, the first cleaning component 2 can move relative to the outer surface of the drum 1 toward the direction close to the center of the cavity 101 to be concave relative to the second cleaning component 6. When the drum 1 is used for cleaning operations, the first cleaning component 2 cannot directly contact the surface to be cleaned or the force between the first cleaning component 2 and the surface to be cleaned is weakened (or the contact is not tight enough). At this time, the second cleaning component 6 located on the outer side wall of the drum 1 can directly contact the surface to be cleaned and perform cleaning on the surface to be cleaned.

[0084] By adjusting the adjusting component 3 to drive the first cleaning component 2 to radially extend or retract, the rotary brush 10 can automatically or manually adjust the cleaning state according to different cleaning scenarios (such as cleaning surfaces of different materials), improving the cleaning efficiency and quality.

[0085] In some embodiments, the surface of the first cleaning component 2 facing away from the cavity 101 is provided with first cleaning bristles 21, and the surface of the second cleaning component 6 facing away from the cavity 101 is provided with second cleaning bristles 61. The hardness of the first cleaning bristles 21 is greater than that of the second cleaning bristles 61.

[0086] The first cleaning bristles 21 have good wear resistance and rigidity and can effectively remove stubborn stains; the second cleaning bristles 61 have excellent flexibility and skin-friendly properties, are suitable for cleaning easily worn surfaces, thus effectively protecting the surface to be cleaned and preventing the surface to be cleaned from being damaged due to excessive friction.

[0087] It should be noted that the materials used to form the first cleaning bristles 21 and the second cleaning bristles 61 are different, so that the first cleaning bristles 21 and the second cleaning bristles 61 have different hardnesses and are suitable for cleaning different surfaces to be cleaned. The user can control and adjust the component 3 to be in the first position or the second position according to different cleaning needs and different surfaces of the surface to be cleaned, so as to control whether the first cleaning component 2 contacts the surface to be cleaned, thereby improving the adaptability of the rotary brush 10 to different surfaces to be cleaned and having different cleaning effects. At the same time, it can also reduce the wear of the first cleaning component 2 on the rotary brush 10 to a certain extent and help extend the service life of the rotary brush 10.

[0088] The following will describe Figures 2 - 9 , the structure of the above-mentioned rotary brush 10.

[0089] Figure 2 FIG. 18 is a schematic structural diagram of the rotary brush 10 provided in an embodiment of the present application in the first state, Figure 3 is Figure 2 a schematic cross-sectional structural diagram of Figure 4 is Figure 2 an assembly schematic diagram of a part of the first cleaning component 2 and the adjusting component 3 in Figure 5 FIG. 28 is a schematic structural diagram of the rotary brush 10 provided in an embodiment of the present application in the second state, Figure 6 is Figure 5 a schematic cross-sectional structural diagram of Figure 7 is Figure 5 an assembly schematic diagram of a part of the first cleaning component 2 and the adjusting component 3 in Figure 8 is Figure 5 an assembly schematic diagram of the adjusting component 3, the drum driving component 7, and the elastic resetting component 5 in Figure 9 FIG. 42 is an assembly schematic diagram of the driving member 4 in the rotary brush 10 provided in an embodiment of the present application.

[0090] Figures 2 - 4 The rotary brush 10 therein is in the first state. At this time, the adjusting assembly 3 is in the first position, and the first cleaning assembly 2 is recessed relative to the installation groove 102 under the drive of the adjusting assembly 3. Figures 5 - 7 The rotary brush 10 therein is in the second state. At this time, the adjusting assembly 3 is in the second position, and the first cleaning assembly 2 protrudes outward relative to the installation groove 102 under the drive of the adjusting assembly 3 and is at least flush with the second cleaning assembly 6.

[0091] The number of the first cleaning assemblies 2 provided in the embodiment of the present application is at least two and they are arranged at intervals in the circumferential direction of the drum 1. Please refer to Figure 2 , from this angle, it can be seen that the rotary brush 10 is a columnar structure as a whole, and at least three installation grooves 102 are formed on its circumferential side wall, and one first cleaning assembly 2 is installed in any one of the installation grooves 102.

[0092] In other similar embodiments, the number of the first cleaning assemblies 2 can be adjusted to be more according to actual needs, such as three, four, five, six, etc.

[0093] In order to enable the first cleaning assembly 2 to have a better cleaning effect, any one of the first cleaning assemblies 2 is provided as a strip structure extending along the axial direction of the drum 1.

[0094] Specifically, the first cleaning assembly 2 can be a linear strip structure. At this time, the length direction of the first cleaning assembly 2 is consistent with the axial direction of the drum 1, or there is an included angle not greater than 30°. When there is an included angle between the first cleaning assembly 2 and the axial direction of the drum 1, at this time, the first cleaning assembly 2 is a spiral structure arranged around the circumferential side of the drum 1. Please refer to Figure 2 .

[0095] The rotary brush 10 further includes a driving and locking member. Please refer to Figure 2 . The driving and locking member is installed at one end of the drum 1 in the axial direction and is connected to the adjusting assembly 3 located in the cavity 101 of the drum 1. The driving and locking member is used to drive the adjusting assembly 3 to move between the first position and the second position, or lock the adjusting assembly 3 at one of the first position and the second position.

[0096] The driving and locking member can ensure that the adjusting assembly 3 is stably held in the required position, and ensure the reliability and stability of the rotary brush 10 during the working process.

[0097] Specifically, in this embodiment, the above-mentioned driving and locking member includes a pull rope 42. One end of the pull rope 42 extends into the drum 1 and is connected to the adjusting assembly 3 for pulling the adjusting assembly 3 to move from the first position to the second position.

[0098] Please refer to Figure 3The driving locking member includes a driving component 4 and an elastic reset component 5, wherein the driving component 4 is used to be connected to the adjusting component 3 to drive the adjusting component 3 to move from the first position to the second position; the elastic reset component 5 is used to control the movement of the adjusting component 3 from the second position to the first position through deformation recovery or deformation, and the elastic reset component 5 can respond to the movement of the adjusting component 3 from the first position to the second position through deformation or deformation recovery.

[0099] Therefore, with the cooperation of the driving member 4 and the elastic return member 5, the adjustment component 3 located in the cavity 101 of the roller 1 can be locked in any one of the first position and the second position, and move between the first position and the second position, so as to facilitate the user to control the extension or retraction of the first cleaning component 2 relative to the roller 1 as needed.

[0100] Specifically, in addition to the pull rope 42, the driving component 4 also includes a transmission-connected winder 41 and a first driving motor 43. The first driving motor 43 is used to drive the winder 41 to rotate. One end of the pull rope 42 is fixed on the winder 41, and the other end extends relative to the winder 41 after rotating several circles around the winder 41 and is connected to the adjustment component 3.

[0101] See also Figure 3 The end of the pull rope 42 extending relative to the winder 41 is provided with a stopper 421 connected to the adjustment assembly 3, and the pull rope 42 passes through the elastic reset member 5 and is connected to the adjustment assembly 3. The elastic reset member 5 includes an end cover 51 and an elastic member 52, and the end cover 51 is provided at one end of the drum 1 to close the above-mentioned cavity 101. At this time, a receiving cavity for receiving the elastic member 52 is formed between the end cover 51 and the adjustment assembly 3, and the elastic member 52 is located in the cavity 101 and abuts against the end cover 51 and the adjustment assembly 3.

[0102] The elastic member 52 can respond to the movement of the adjustment component 3 from the first position to the second position by deformation, and can also control the movement of the adjustment component 3 from the second position to the first position by deformation recovery.

[0103] When the adjustment component 3 is in the first position, the elastic member 52 is in a normal state or a compressed state as a whole. When the adjustment component 3 moves from the first position to the second position under the drive of the driving member 4, the adjustment component 3 moves along the axial direction of the drum 1 toward the side close to the end cover 51, the space formed between the adjustment component 3 and the end cover 51 is reduced, the elastic member 52 is compressed and deformed, and a certain amount of elastic potential energy is accumulated in this process. When the adjustment component 3 is in the second position, the elastic member 52 is compressed and deformed to the highest degree, and the continuous elastic potential energy is the largest.

[0104] When the driving force applied by the driving member 4 is removed, at this time, the pulling rope 42 no longer applies a pulling force to the adjusting member, and the elastic member 52 located between the adjusting assembly 3 and the end cover 51 deforms and recovers to release elastic potential energy. Under the action of the elastic potential energy, the adjusting assembly 3 moves axially along the roller 1 toward the side away from the end cover 51, and the space formed between the adjusting assembly 3 and the end cover 51 gradually increases.

[0105] The elastic reset member 5 can not only reset the adjusting assembly 3 without additional power, saving energy, but also make the reciprocating movement of the adjusting assembly 3 smoother and more stable.

[0106] Specifically, the above elastic member 52 can be a spring. A first abutting surface for abutting against one end of the spring is formed on the side of the end cover 51 facing the inner cavity 101 of the roller 1, and a second abutting surface for abutting against the spring is formed on the side of the adjusting assembly 3 facing the end cover 51. The spring can be fixed between the end cover 51 and the adjusting assembly 3 through the first abutting surface and the second abutting surface respectively, and is compressed and deformed when the adjusting assembly 3 moves from the first position to the second position, and pushes the adjusting assembly 3 to move from the second position to the first position through deformation recovery.

[0107] Of course, in other similar embodiments, it can also be set that the above driving locking member further includes a magnetic attraction structure. The magnetic attraction structure includes a first magnetic attraction member and a second magnetic attraction member with mutually repulsive magnetism, and the first magnetic attraction member and the second magnetic attraction member are respectively arranged on the adjusting assembly 3 and the end cover 51. When the elastic member 52 controls the adjusting assembly 3 to move from the second position to the first position through deformation recovery, the first magnetic attraction member and the second magnetic attraction member with mutually repulsive magnetism can help push the adjusting assembly 3 to quickly move to the first position, so as to improve the displacement speed of the adjusting assembly 3 and help improve the stability of the movement process of the adjusting assembly 3.

[0108] Alternatively, it can also be set that the magnetic attraction structure includes a first magnetic attraction member and a second magnetic attraction member with mutually attracting magnetism, and the first magnetic attraction member and the second magnetic attraction member are respectively arranged on the adjusting assembly 3 and the end cover 51. When the driving member 4 pulls the adjusting assembly 3 to move from the first position to the second position through the pulling rope 42, the above magnetic attraction structure can provide a force in the same direction as the pulling force of the pulling rope 42 to the adjusting assembly 3 to a certain extent, so as to help reduce the load of the first driving motor 43, thereby accelerating the displacement speed of the adjusting assembly 3 from the first position to the second position, and helping to reduce the friction of the pulling rope 42 in this process, so as to extend the service life of the pulling rope 42. Of course, the maximum magnetic attraction force that the magnetic structure in this embodiment can provide is less than the thrust provided by the elastic member 52 to the adjusting assembly 3 to avoid affecting the normal movement of the adjusting assembly 3.

[0109] When the adjusting assembly 3 moves from the first position to the second position, please refer to Figure 5 and Figure 6, at this time, the adjusting assembly 3 moves relative to the drum 1 toward the side close to the end cover 51, and the first cleaning assembly 2 connected to the adjusting assembly 3 extends radially outward of the drum 1 along the mounting groove 102 formed in the drum 1.

[0110] When the adjusting assembly 3 moves between the first position and the second position, since the adjusting assembly 3 moves along the axial direction of the drum 1 and the first cleaning assembly 2 moves along the radial direction of the drum 1, the relative position between the adjusting assembly 3 and the first cleaning assembly 2 also changes to a certain extent. Please refer to Figure 4 and Figure 7 .

[0111] Specifically, the adjusting assembly 3 is movably connected to the side of the first cleaning assembly 2 facing the inside of the drum 1.

[0112] Please refer to Figure 4 and Figure 7 , the adjusting assembly 3 includes a movable frame and a connecting rod. The movable frame is integrally in a columnar structure, and one end in its axial direction is fixedly connected to the limiting block 421 of the pulling rope 42. The connecting rod is movably installed on the circumferential outer wall of the movable frame and is movably connected to the first cleaning assembly 2.

[0113] Specifically, both ends of the connecting rod are hinged to the movable frame and the first cleaning assembly 2 respectively. When the movable frame moves between the first position and the second position along the axial direction of the drum 1, the connecting rod can pull the first cleaning assembly 2 to extend or retract relative to the mounting groove 102.

[0114] Please refer to Figure 4 , at this time, the movable frame is located at the first position, the connecting rod on the circumferential side of the movable member is inclined toward one end relative to the movable frame, and the movable frame is offset to the left in the illustrated orientation relative to the first cleaning assembly 2; please refer to Figure 7 , at this time, the movable member moves to the second position to the right in the illustrated orientation relative to the first cleaning assembly 2, the connecting rod on the circumferential side of the movable frame points radially outward relative to the movable frame, and the first cleaning assembly 2 can extend radially outward along the drum 1 through the mounting groove 102 under the push of the connecting rod.

[0115] The number of connecting rods in the adjusting assembly 3 provided in the embodiment of the present application is an integer multiple of the number of the first cleaning assemblies 2. Please refer to Figure 4 and Figure 7 , the maximum number of the first cleaning assemblies 2 in the figure is six (for the convenience of observing the structure of the adjusting assembly 3, Figure 4 only four are drawn in Figure 7 and only five are drawn in

[0116] Of course, the rotary brush 10 further includes a drum drive assembly 7 for driving the rotation of the drum 1. At least part of the drum drive assembly 7 is installed in the cavity 101 and is slidably engaged with the adjustment assembly 3 through a drive end.

[0117] It should be noted that during the movement of the adjustment assembly 3 between the first position, the second position, and between the first position and the second position, the drum drive assembly 7 can always maintain a transmission connection with the adjustment assembly 3, so as to ensure that the rolling drive assembly can always synchronously drive the drum 1 and the first cleaning assembly 2 located on the drum 1 to rotate synchronously and clean the surface to be cleaned.

[0118] The drum drive assembly 7 is installed inside the drum 1. Please refer to Figure 3 and Figure 6 .

[0119] Specifically, the drum drive assembly 7 is located at one end of the adjustment assembly 3 facing away from the elastic reset member 5, and includes a second drive motor 71 and a reduction gear 72 that are drivingly connected. Along the axial direction of the drum 1, one end of the reduction gear 72 is drivingly connected to the output end of the second drive motor 71, and the other end serves as a drive end and is slidably engaged with the adjustment assembly 3.

[0120] Please refer to Figure 8 , for the convenience of observation, Figure 8 only the drive end of the drum drive assembly 7 is drawn in

[0121] , and only a partial structure of the elastic reset member 5 is drawn. Along the axial direction of the adjustment assembly 3, one end is used to connect to the drum drive assembly 7, and the other end is used to connect to the elastic reset member 5. Along the moving direction of the adjustment assembly 3, that is, the axial direction of the drum 1, at least three strip-shaped guide grooves are formed on the outer side wall of the drive end of the drum drive assembly 7. Correspondingly, the movable member of the adjustment assembly 3 is sleeved on one end of the drive end to form a mating hole that mates with the drive end, and guide protrusions that mate with the guide grooves are protruded on the inner side wall of the mating hole.

[0122] Compared with other similar embodiments, the rotary brush 10 provided in this embodiment can not only be installed with the first cleaning assembly 2 and the second cleaning assembly 6 with different cleaning effects at the same time, improving the use flexibility of the drum 1, but also can lock the position of the first cleaning assembly 2, further improving the use effect of the drum 1.

[0123] In order to facilitate the user to adjust the position of the first cleaning component 2 according to cleaning needs, in some embodiments, the adjustment of the first cleaning component 2 can be set to be achieved manually or automatically.

[0124] Exemplarily, when the position of the first cleaning component 2 needs to be manually controlled, the driving member 4 is provided to include a connected controller and control buttons.

[0125] Specifically, the control button is used to output an operation instruction to the controller after being pressed; the controller is electrically connected to the first drive motor 43, and is used to generate a drive signal in response to the operation instruction, and output the drive signal to the first drive motor 43, so that the first drive motor 43 drives the winder 41 to rotate or stop according to the drive signal.

[0126] In this embodiment, the driving signal is defined to include a first driving signal and a second driving signal: the first driving signal is used to control the first driving motor 43 to rotate forward, and the second driving signal is used to control the second driving motor 71 to rotate reversely.

[0127] In response to the first driving signal output by the controller, the first driving motor 43 rotates forward and drives the winder 41 to rotate forward. At this time, the pull rope 42 connected to the winder 41 can pull the adjusting component 3 toward the side close to the elastic reset member 5 and squeeze the spring; in response to the second driving signal output by the controller, the second driving motor 71 rotates reversely and drives the winder 41 to rotate reversely. At this time, the external force applied to the adjusting component 3 by the pull rope 42 connected to the winder 41 is removed, and the spring pushes the adjusting component 3 to reset by means of deformation recovery. The limiter connected to the adjusting component 3 can pull the pull rope 42 to move into the drum 1, so that the part of the pull rope 42 located outside the drum 1 remains straight or in a normally propped up state.

[0128] In some embodiments, the driving signal further includes a third driving signal, and the third driving signal is used to control the first driving motor 43 to stop working. At this time, the first driving motor 43 is stationary and locks the adjusting component 3 in the first position or the second position according to the different positions of the adjusting component 3.

[0129] The control buttons and controller cooperate with each other to accurately control the movement state of the adjustment component 3.

[0130] In this embodiment or other similar embodiments, the driving member 4 may also include a detection component electrically connected to the controller. The detection component is used to obtain cleaning information and output an operation instruction to the controller based on the cleaning information. The controller may respond to the operation instruction to generate and output a first driving signal, and the first value motor may drive the winder 41 to rotate (including forward rotation and reverse rotation) or stop according to the driving signal.

[0131] Specifically, the cleaning information includes at least one of the type of the surface to be cleaned, the cleanliness of the surface to be cleaned, the dirtiness of the cleaning liquid, and the dirtiness of the roller brush 10.

[0132] The above-mentioned cleaning information can be obtained through corresponding sensors, and its structure and connection method have been disclosed in the related art, so details are not described herein again.

[0133] In order to further improve the use effect of the roller brush 10, in a feasible implementation manner, the driving member 4 further includes a quick-release member 44. The quick-release member 44 includes a first joint 441 and a second joint 442 that cooperate with each other. The first joint 441 is disposed on the first driving motor 43, and the second joint 442 is disposed on the winder 41. Please refer to Figure 9 .

[0134] The first joint 441 and the second joint 442 are in pluggable and unplugable cooperation to realize the detachable connection between the first driving motor 43 and the winder 41.

[0135] The quick-release member 44 enables the user to easily remove the winder 41 from the first driving motor 43. This structure not only facilitates the user to replace the winder 41 or the pull rope 42 wound around the winder 41 as needed, but also helps to achieve the quick-release design of the roller brush 10 (the winder 41 is connected to the roller brush 10 through the pull rope 42, and separating the winder 41 from the first driving motor 43 can remove the roller brush 10 from the cleaning device 100), which helps to reduce the difficulty for the user to remove the roller brush 10 from the cleaning device 100, facilitating the user to perform daily maintenance or cleaning on the roller brush 10, improving the operation convenience, and lowering the usage threshold of the product.

[0136] It can be understood that, through Figures 2 - 9 the embodiments of the present application provide a roller brush 10 that can automatically control the first cleaning assembly 2 to extend or retract relative to the drum 1 by the first driving motor 43 and can be locked in the corresponding state. For the user, by adjusting the extension or retraction of the first cleaning assembly 2 relative to the drum 1, the roller brush 10 can have different cleaning effects, effectively overcoming the defects of the traditional roller brush 10 with a single cleaning effect and the need to manually replace the roller brush 10 to achieve different cleaning effects, and improving the use experience of the roller brush 10.

[0137] In other similar embodiments, the embodiments of the present application also provide a structure of the roller brush 10 that can manually control the first cleaning assembly 2 to extend or retract relative to the drum 1 and can be locked in the corresponding state. Please refer to Figures 10 - 21 .

Figure 11 is a schematic structural diagram of the roller brush 10 provided in another embodiment of the present application in the first state.Figure 10 Schematic cross-sectional structure diagram Figure 12 is Figure 10 Assembly schematic diagram of part of the first cleaning component 2 and the adjusting component 3 in Figure 13 is Figure 10 Assembly schematic diagram of the adjusting component 3, the drum drive component 7, and the elastic reset component 5 in Figure 14 is Figure 10 Structure diagram of the driving member 4 in Figure 15 is Figure 14 Explosion diagram of Figure 16 is Figure 14 Partial inner surface plane development diagram of the guiding member 45 in Figure 17A - Figure 17C is Figure 14 Illustration of the action relationship of the locking cam 47 with the pressing member 46 and the guiding member 45 in Figure 18 is Figure 10 Schematic cross-sectional structure diagram of the force-applying member 48 in Figure 19 Schematic structure diagram of the roller brush 10 provided by another embodiment of the present application in the second state Figure 20 is Figure 19 Schematic cross-sectional structure diagram of Figure 21 is Figure 19 Assembly schematic diagram of part of the first cleaning component 2 and the adjusting component 3 in

[0139] Please refer to Figure 10 , at this time, the roller brush 10 replaces the original pulling rope 42 and end cap 51 structure through the force-applying member 48 located at one end of the drum 1.

[0140] Please refer to Figure 11 , the adjusting component 3 described above is provided inside the roller brush 10, and the elastic reset component 5 includes an elastic member 52 located at one end of the adjusting component 3 facing away from the driving member 4 (i.e., the force-applying component).

[0141] Specifically, the elastic member 52 is located between the output end of the drum drive component 7 and the adjusting component 3. When the adjusting component 3 moves from the second position to the first position, the distance between the adjusting component 3 and the output end gradually decreases, and the elastic member 52 is in a compressed deformation state; when the adjusting component 3 moves from the first position to the second position, the distance between the adjusting component 3 and the output end gradually increases, and at this time, the elastic member 52 is in a state of deformation recovery.

[0142] Since the position of the elastic member 52 changes greatly relative to the adjusting component 3, therefore, in this embodiment, the elastic member 52 responds to the movement of the adjusting component 3 from the second position to the first position through deformation, and the elastic member 52 controls the movement of the adjusting component 3 from the first position to the second position through deformation recovery.

[0143] Specifically, the elastic member 52 can be a spring. The two ends of the spring in the axial direction are respectively in abutting connection with the driving end of the drum driving assembly 7 and the adjusting assembly 3.

[0144] Please refer to Figure 11 and Figure 12 , the adjusting assembly 3 includes a movable frame and a connecting rod. The movable frame is hinged to the first cleaning assembly 2 through the connecting rod, and the connection method is the same as that described above, and will not be elaborated here.

[0145] In the embodiment of the present application, the assembly structure of the adjusting assembly 3 and the drum driving assembly 7 is the same as that described above, and will not be elaborated here. In addition, an elastic member 52 is also provided at the connection between the adjusting assembly 3 and the drum driving assembly 7. Please refer to Figure 13 . A space for accommodating the elastic member 52 is recessed on the inner wall of one side of the adjusting assembly 3 close to the driving end of the drum driving assembly 7. As the adjusting assembly 3 slides relative to the driving end of the drum driving assembly 7, the elastic reset member 5 is in a compressed deformation state or a state of deformation recovery. Of course, in this embodiment, the elastic member 52 can be in an uncompressed state or in a state with a small extrusion force when the adjusting assembly 3 is in the second position, and this embodiment does not limit it. Of course, considering that the first cleaning assembly 2 will directly contact the surface to be cleaned and provide a certain extrusion force and friction force to the surface to be cleaned during cleaning, the elastic member 52 is generally set to be in a state of extrusion deformation all the time, and when the adjusting assembly 3 is in the second position, the extrusion force received by the elastic member 52 is less than the extrusion force received when the adjusting assembly 3 is in the first position.

[0146] In order to conveniently control the relative state between the first cleaning assembly 2 and the drum 1 by manual adjustment, a new driving member 4 is provided in this embodiment. Please refer to Figures 14 - 15 , the driving member 4 includes a guiding member 45, a pressing member 46 and a locking cam 47. The three cooperate with each other and can be locked at two different positions respectively under the pressing action of an external force, so as to drive the adjusting assembly 3 to be locked and fixed at the first position or the second position.

[0147] Specifically, the guiding member 45 is installed at one end of the drum 1 in the axial direction, and at least part of its structure can extend into the cavity 101 of the drum 1 and is connected to one end of the adjusting assembly 3 located in the cavity 101 in a plugging manner. Please refer to Figure 15 , along the axial direction of the guiding member 45, a guiding hole 451 is opened at one end of the guiding member 45 close to the adjusting assembly 3. The axis of the guiding hole 451 is on the same straight line as the axis of the adjusting assembly 3, that is, the guiding hole 451 is coaxially arranged with the cavity 101. At least two guiding members 452 extending along the axial direction of the guiding hole 451 are convexly provided on the inner side wall of the guiding hole 451 (of course, it can also be understood that at least two guiding grooves extending along the axial direction of the guiding hole 451 are recessed on the inner side wall).

[0148] Specifically, the number of the guiding members 452 may be two, three, four or even more. Refer to Figure 15 , in the figure, the number of the guiding members 452 is three and they are arranged at intervals, and the distance between any two adjacent guiding members 452 is equal. In addition, a circumferential limiting ring 454 perpendicular to the guiding members 452 is formed on the inner side wall of the guiding member 45.

[0149] The pressing member 46 can be installed in the guiding member 45 through the guiding hole 451 and is in sliding fit with the guiding member 45 through the guiding members 452. Refer to Figure 14 and Figure 15 , the pressing member 46 slidably disposed in the guiding hole 451 of the guiding member 45 can axially slide relative to the guiding member 45. Meanwhile, under the limiting and guiding action of the guiding members 452, the pressing member 46 will not rotate circumferentially relative to the guiding member 45.

[0150] Specifically, the pressing member 46 is integrally of a hollow columnar structure, and a part of the outer side wall of the end thereof close to the adjusting assembly 3 bulges radially outward to form a plurality of first protruding structures arranged at intervals. The number of the first protruding structures is the same as that of the guiding members 452 and they cooperate with each other. When the pressing member 46 is slidably disposed in the adjusting assembly 3, the first protruding structures formed on the circumferential side wall of the pressing member 46 are limited between two adjacent guiding members 452, and the guiding members 452 pass through two adjacent first protruding structures and are in snap fit with the outer side wall of the pressing member 46 to limit the circumferential rotation of the pressing member 46 relative to the guiding member 45.

[0151] The locking cam 47 is located at the end of the pressing member 46 close to the adjusting assembly 3 and at least part of it can be inserted into the guiding hole 451. Similarly, the locking cam 47 is in sliding fit with the guiding members 452 to axially slide along the guiding member 45 under the push of an external force.

[0152] Specifically, the locking cam 47 is also integrally of a columnar structure. The end thereof close to the pressing member 46 can extend into the pressing member 46, and the other end (i.e., the end close to the adjusting assembly 3) also bulges radially outward to form a second protruding structure. The number of the second protruding structures is the same as that of the guiding members 452 and they cooperate with each other. The locking cam 47 can cooperate with the first protruding structures of the pressing member 46 through the second protruding structures, so as to push the adjusting assembly 3 to move from the second position to the first position under the push of the pressing member 46.

[0153] Correspondingly, with the cooperation of the elastic resetting member 5, the adjusting assembly 3 can move from the first position to the second position and push the locking cam 47 and the pressing member 46 to return to the initial state in this process.

[0154] To facilitate the movement of the adjustment assembly 3 between the first position and the second position and the locking at the first position and the second position through the above-mentioned driving member 4 and the elastic reset member 5, the driving member 4 further includes guiding side walls respectively formed on the guiding member 45, the pressing member 46, and the locking cam 47.

[0155] Please refer to Figure 15 , Figure 16 , Figure 17A , Figure 17B and Figure 17C , the guiding member 45 has a first guiding side wall 453, the first guiding side wall 453 is formed at one end of any guiding member 452 pointing to the adjustment assembly 3, and along the circumference of the guiding hole 451 in the guiding member 45, all the first guiding side walls 453 incline in the same direction. One end of the locking cam 47 facing the guiding member 45, that is, one end of the second convex structure facing the guiding member 452, has a second guiding side wall 471, and the second guiding side wall 471 is inclined in the same direction as the first guiding side wall 453. One end of the pressing member 46 facing the locking cam 47, that is, one end of the first convex structure facing the locking cam 47, has a third guiding side wall 461, and at least part of the side wall of the third guiding side wall 461 inclines in the same direction as the first guiding side wall 453.

[0156] It should be noted that along the circumference of the guiding hole 451, the third guiding side wall 461 and the first guiding side wall 453 are arranged in an interleaved manner.

[0157] For the cooperation mode of the guiding member 45, the pressing member 46, and the locking cam 47, please refer to Figure 17A , Figure 17B , Figure 17C and Figure 17D , wherein, in the state shown in Figure 17A , the adjustment assembly 3 is located at the first position; in the states shown in Figure 17B and Figure 17D , the adjustment assembly 3 is located between the first position and the second position; in the state shown in Figure 17C , the adjustment assembly 3 is located at the second position.

[0158] When the adjustment assembly 3 is located at the first position, at this time, the driving member 4 abuts against one side of the adjustment assembly 3 facing the driving member 4 through the locking cam 47, and the elastic member 52 at the other end of the adjustment assembly 3 is in a deformed state under force and stores a certain amount of elastic potential energy. At this time, for the cooperation mode of the guiding member 45, the pressing member 46, and the locking cam 47, please refer to Figure 17A, the second guiding side wall 471 of the locking cam 47 abuts against the first guiding side wall 453 of the guiding member 45. At this time, the locking cam 47 abuts against the guiding member 452 of the guiding member 45 through the second guiding side wall 471. The pressing member 46 is located at one end of the locking cam 47 facing away from the adjusting assembly 3 and can freely move axially along the guiding member 45 within the region defined by the second protruding structure of the locking cam 47 and the circumferential limiting ring 454 of the guiding member 45. Of course, when only the first protruding structure of the pressing member 46 can be accommodated within the region defined by the two, the pressing member 46 cannot move axially relative to the guiding member 45 without external force driving.

[0159] Subsequently, an external force can be applied to the pressing member 46 to drive the pressing member 46 to move axially along the guiding member 45 towards the end close to the adjusting assembly 3. During the movement of the pressing member 46, the pressing member 46 can be in contact with the locking cam 47 through the contact between the third guiding side wall 461 and the second guiding side wall 471 of the locking cam 47. As the pressing member 46 continues to move, the pressing member 46 can push the locking cam 47 to move synchronously and separate from the first guiding side wall 453 of the guiding member 45. Since the second guiding side wall 471 and the first guiding side wall 453 are arranged in an interleaved manner, the locking cam 47 separated from the first guiding side wall 453 can, during the continuous movement, separate from the guiding member 452 of the guiding member 45 and rotate a certain angle relative to the guiding member 45 around its circumference under the guidance of the second guiding side wall 471 until the second guiding side wall 471 of the locking cam 47 is at least partially in contact with or completely abuts against the third guiding side wall 461 of the pressing member 46. Please refer to Figure 17B . At this time, the locking cam 47 can be pushed by the pressing member 46 to get rid of the circumferential limitation of the guiding member 452 on the locking cam 47 and guide the locking cam 47 to rotate a certain angle relative to the guiding member 45.

[0160] It should be noted that the inclination angle of the third guiding side wall 461 can be the same as or different from the inclination angle of the second guiding side wall 471. In this embodiment, the third guiding side wall 461 is only used to provide a force for the locking cam 47 to rotate a certain angle along the inclination direction of the third guiding side wall 461, and is not used to directly limit the actual rotation angle of the locking cam 47.

[0161] Finally, remove the external force applied to the pressing member 46. At this time, the elastic member 52 located at the other end of the adjusting assembly 3 deforms and recovers, releasing elastic potential energy to push the adjusting assembly 3 towards the second position. During this process, the adjusting assembly 3 can push the locking cam 47 to move synchronously in the same direction. At this time, the locking cam 47 can synchronously push the pressing member 46 to move synchronously in the same direction until the second guiding side wall 471 of the locking cam 47 contacts the first guiding side wall 453 of the guiding member 452. Under the guidance of the first guiding side wall 453, the locking cam 47 can further rotate around the axis by a certain angle until the guiding member 452 can be inserted between two adjacent second protruding structures of the locking cam 47. At the same time, the locking cam 47 continues to move along the axial direction of the guiding member 45 and abuts against the third guiding side wall 461 formed on the pressing member 46. At this time, under the push of the elastic member 52 and the locking of the locking cam 47, the adjusting assembly 3 is limited to the second position.

[0162] When it is necessary to control the movement of the adjusting assembly 3 from the second position to the first position, only need to continue to apply pressure to the pressing member 46. The pressing member 46 can again push the locking cam 47 to move along the axial direction of the guiding member 45 through the third guiding side wall 461 until it separates from the guiding member 452 and then rotates around the axis by a certain angle. Please refer to Figure 17D Figure. During the rotation process, the locking cam 47 can move a certain distance towards the side close to the guiding member 452 under the thrust provided by the elastic member 52, and make the second guiding side wall 471 formed on the second protruding structure contact the first guiding side wall 453 formed on the guiding member 452. At this time, the adjusting assembly 3 is again limited to the first position under the push of the elastic member 52 and the locking of the locking cam 47. Please refer to Figure 17A Figure.

[0163] That is to say, the locking cam 47 can rotate around the axial direction of the guiding member 45 with the third guiding side wall 461 formed on the pressing member 46 as the axis until it contacts the first guiding side wall 453 and locks the adjusting assembly 3 at the first position; the locking cam 47 can rotate around the axial direction of the guiding member 45 with the third guiding side wall 461 formed on the pressing member 46 as the axis until it is in sliding fit with the guiding member 452, and push the adjusting assembly 3 to move and be limited to the second position under the push of the elastic member 52.

[0164] Since the pressing member 46 is inserted into the guiding hole 451 of the guiding member 45, in order to facilitate the user to operate the pressing member 46 and apply pressure to the pressing member 46, in some embodiments, the guiding hole 451 of the guiding member 45 may be provided to penetrate through the guiding member 45, and one end of the pressing member 46 facing away from the adjusting assembly 3 extends outwards along the guiding hole 451 and is exposed relative to the guiding member 45. Alternatively, in other similar embodiments, the driving member 4 is provided to further include a force applying member 48 that abuts against the pressing member 46. The force applying member 48 can pass through the guiding member 45 and abut against the pressing member 46 located within the guiding member 45, so as to facilitate the user to apply a thrust force to the pressing member 46 to move it towards the position closer to the adjusting assembly 3.

[0165] Specifically, please refer to Figure 18 , the force applying member 48 includes a cooperating pressing limit cover 481, a force applying block 482, and a transmission block 483. Among them, the pressing limit cover 481 is fixedly installed at one end of the drum 1 and closes the guiding member 45. A through hole communicating with the guiding hole 451 in the guiding member 45 is provided in the middle of the pressing limit cover 481. The force applying block 482 and the transmission block 483 are fixedly connected. The force applying block 482 is located on the side of the pressing limit cover 481 facing away from the guiding member 45. One end of the transmission block 483 is fixedly connected to the force applying block 482, and the other end passes through the through hole and extends into the guiding hole 451 of the guiding member 45 to abut against the pressing member 46.

[0166] The user can apply a certain pressure to the pressing member 46 by pressing the force applying block 482, so as to push the pressing member 46 to drive the locking cam 47 to move towards the side closer to the adjusting assembly 3. During this process, the locking cam 47 is guided to rotate a certain angle around the axis through the cooperation of the guiding member 45 and the elastic member 52, so as to switch the cooperation relationship between the locking cam 47 and the guiding member 45. Furthermore, during this process, the adjusting assembly 3 is controlled to move between the first position and the second position and finally lock the adjusting assembly 3 at one of the first position and the second position.

[0167] Through the above operations, the adjusting assembly 3 can be moved from the first position to the second position and locked.

[0168] When the adjusting assembly 3 is in the second position, for the structure of the roller brush 10, please refer to Figure 19 and Figure 20 , at this time, the first cleaning assembly 2 extends radially outwards relative to the mounting groove 102.

[0169] For the structure of the adjusting assembly 3 located within the drum 1, please refer to Figure 21 , one end of the swing arm on the outer peripheral side of the movable frame connected to the first cleaning assembly 2 points to the radial outside of the movable frame.

[0170] The above process will be described from the perspective of the user as follows:

[0171] In the initial state, the adjustment assembly 3 is located in the first position. When in use, the pressing member 46 can slide and move along the guide member 452 of the inner side wall of the guide hole 451 in the guide member 45 by pressing the force block 482, and push the locking cam 47 to move synchronously, at which time the elastic member 52 is deformed by pressure and accumulates elastic potential energy. After the locking cam 47 moves to the end of the guide member 452, the third guide side wall 461 formed at the end of the pressing member 46 can be partially staggered with the second guide side wall 471 formed on the locking cam 47, and the locking cam 47 can rotate along its circumferential direction under the guidance of the third guide side wall 461. At the same time, the locking cam 47 no longer applies an extrusion force to the elastic member 52 in the axial direction, and the elastic member 52 releases a certain amount of elastic potential energy, so that the locking cam 47 can be against the third guide side wall 461 again while rotating in the circumferential direction (at this time, the locking cam 47 and the pressing member 46 are against each other and a "click" sound is emitted). Finally, the force of the pressing force block 482 is removed, and the spring releases its elastic potential energy again and pushes the adjustment component 3 and the locking cam 47 to move axially. The locking cam 47 can push the pressing component 46 to reset and continue to rotate a certain angle under the guidance of the first guide side wall 453 formed on the guide member 452 and slide with the guide member 452 (the locking cam 47 is attached to the first guide side wall 453 of the guide member 452 through the second guide side wall 471 and rotates under the guidance of the second guide side wall until the two are separated, making a "click" sound).

[0172] Through a single pressing operation, the adjustment component 3 can be controlled to move from the first position to the second position and locked. At this time, the adjustment position is fixed at the second position, and the first cleaning component 2 connected thereto is driven to remain extended relative to the mounting slot 102 .

[0173] Press the force - applying block 482 again. As described above, at this time, the pressing member 46 can slide along the guiding member 452 and push the locking cam 47 to move synchronously. At this time, the elastic member 52 is compressed and deformed to store elastic energy release. After the locking cam 47 moves to the end of the guiding member 452, the first guiding side wall 453 formed at the end of the guiding member 452 and the second guiding side wall 471 formed on the locking cam 47 just meet and incline in the same direction. With the continuous movement of the pressing member 46, the locking cam 47 is disengaged from the guiding member 452 and is not restricted by the guiding member 452 in its circumferential direction. At this time, the locking cam 47 can rotate relative to the pressing member 46 by a certain angle so that the second guiding side wall 471 can at least partially contact and abut against the third guiding side wall 461 (at this time, the locking cam 47 abuts against the pressing member 46 and makes a "click" sound); then, remove the external force applied to the force - applying block 482, and the elastic member 52 will release a certain amount of elastic energy release and push the adjusting assembly 3 and the locking cam 47 to move axially. When the locking cam 47 moves to just contact the guiding member 452, at this time, the locking cam 47 can rotate along its circumferential direction under the guidance of the first guiding side wall 453 to separate from the third guiding side wall 461 of the pressing member 46. During the rotation, the elastic member 52 will continue to release a certain amount of elastic potential energy to push the locking cam 47 to rotate in the circumferential direction by a certain angle and then abut against the first guiding side wall 453 located at the end of the guiding member 452 again (at this time, the locking cam 47 abuts against the guiding member 452 and makes a "tick" sound) to lock the locking cam 47.

[0174] Through the second pressing operation, the adjusting assembly 3 can be controlled to move from the second position to the first position and be locked. At this time, the adjustment position is fixed at the first position, and the first cleaning assembly 2 connected thereto is driven to maintain the retracted / retracted state relative to the installation groove 102.

[0175] Repeat the above process to switch the locking position of the adjusting assembly 3 and control the first cleaning assembly 2 to extend or retract relative to the installation groove 102.

[0176] It can be understood that in the embodiment of the present application, by Figures 10 - 21 a roller brush 10 is provided, which can manually control the first cleaning assembly 2 to extend or retract relative to the roller 1 by a pressing - switching method and can be locked in the corresponding state. For users, by adjusting the first cleaning assembly 2 to extend or retract relative to the roller 1, the roller brush 10 can have different cleaning effects, effectively overcoming the defects of the traditional roller brush 10 with a single cleaning effect and the need to manually replace the roller brush 10 to achieve different cleaning effects, and improving the use experience of the roller brush 10.

[0177] Based on the same inventive concept, in a second aspect, an embodiment of the present application further provides a cleaning device 100, which includes the roller brush 10 described in any one of the above items.

[0178] The roller brush 10 is used to directly contact the surface to be cleaned when the cleaning device 100 performs cleaning operations. At this time, the position of the first cleaning component 2 on the roller brush 10 can be adjusted according to cleaning needs to provide at least two different cleaning modes or cleaning effects for the surface to be cleaned, thereby improving the user experience.

[0179] The above description of various embodiments tends to emphasize the differences between the various embodiments. The same or similar parts can be referenced to each other, and for the sake of brevity, they will not be repeated in this article.

[0180] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
